## Subtracting 10 From 100 Riddle

Hint:

Did you answer this riddle correctly?
YES  NO

Hint:
The best answer from the choices is the owner lost \$100. The \$100 bill that was stolen was then given back to the owner. What the owner loses is the \$70 worth of goods and the \$30 in change, which makes for a total of \$70 + \$30 = \$100. The owner has lost \$100.

Technically, the owner lost \$30 plus the value, V, of the \$70 of goods. Since stores typically sell goods at a markup, the value may be less than \$70. But in the case of a loss leader, the owner may have lost more than \$70.

## 100 Blank Cards Riddle

Hint: Perhaps thinking in terms of one deck is the wrong approach.
Yes!

A sample strategy:
Divide the deck in half and turn over all lower 50 cards, setting aside the highest number you find. Then turn over the other 50 cards, one by one, until you reach a number that is higher than the card you set aside: this is your chosen "high card."

Now, there is a 50% chance that the highest card is contained in the top 50 cards (it is or it isn't), and a 50% chance that the second-highest card is contained in the lower 50. Combining the probabilities, you have a 25% chance of constructing the above situation (in which you win every time).

This means that you'll lose three out of four games, but for every four games played, you pay \$40 while you win one game and \$50. Your net profit every four games is \$10.

Obviously, you have to have at least \$40 to start in order to apply this strategy effectively.
